CS-423E ASH

------ WARNING! ------

机器突然动作,会导致人员伤亡。

机器突然移动,会对机上或机器近处的人员造成伤害。

为避免伤亡事故,开动机器之前,确保机器周围无人及没有各种障碍物。



注意

为避免在测试中损坏振动系统,进行测试时始终将振动钢轮置于轮胎的顶部或松土上。轮胎可以模拟未压实的土壤条件。

当机器处于混凝土上时,严禁操作振动系统。



注意

当需要的测试时间长于三 (3) 分钟时,周期性旋转钢轮以润滑偏心配重轴的轴承。

  1. 从磁性传感器 (2) 的顶部拆下护罩 (1) 。

  1. 拆下橡胶防尘罩。 将两条导线从磁性传感器上断开。

  1. 选择万用表上的电阻档。 将万用表表笔连接在磁性传感器的端子上。 电阻应为 265 ± 30 欧姆。 如果电阻值正确,则转至步骤 4。 如果阻值不正确,则更换磁性传感器。 更换磁性传感器后,转至步骤 11 并调整气隙。

  1. 将万用表设定到最高电阻档。 将万用表的一根表笔连接在磁性传感器的一个端子上。 使另一根表笔接触磁性传感器壳体。

  1. 电阻值应为无穷大。 如果万用表显示了任何读数,都应更换磁性传感器。 更换磁性传感器后,转至步骤 11 并调整气隙。

  1. 选择万用表上的 AC 电压模式。 将万用表的两根表笔连接在磁性传感器的端子上。

  1. 起动发动机并以高怠速运转。

  1. 将振幅控制置于低振幅位置。

  1. 将推进操纵杆上的振动控制开关按到 ON 位置,以起动振动系统。 万用表的指示应当约为 2 ACV。

  1. 如果没有获得该读数,可能需要调整和/或更换磁性传感器。 将推进操纵杆上的振动控制开关按到 OFF 位置,以关闭振动系统。 停止发动机。

  1. 要想调整间隙,松开锁紧螺母后顺时针转动磁性传感器,直到传感器接触到齿轮。 逆时针旋转磁性传感器一整圈。 传感器端部和齿轮轮齿之间的间隙应当为 1.57 mm (0.062 in)。 拧紧锁紧螺母。

  1. 获得正确的读数后,拆下工具并重新安装紧固件。
